The standard C6 just got a bump to 430 (436) and a new engine. When can we expect to see the Z get a nice 25 to 40 hp bump?? I'm eyeing an 08 next but wouldn't mind waiting if something is looming on the horizon.

PS- I know the ZR1 will have 650 hp - I'm talking strictly Z06.

Just wondering since the new Viper with 600 hp is just a hair quicker (about 1/10 in the 1/4 according to Car & Driver) then the current 505 hp Z- wouldn't it be wise if Chevy extracted a bit more power from the LS7? A slightly beefier cam and slight intake and head work would get it done, right?

i dont think they will bump power for the C6Z. 2011 is the C7 and oil price permitting, there might be a power bump. only reason the 02 z got a bump was because catalytic technology improved to loosen the bottle neck thus they were able to use a slightly larger cam.

There will probably be a bump for 09 due to the new Viper.

I talked with Tadge Juechter about this at the 2007 birthday bash in april at B.G. He said the Z gets performance upgrades for 2009,He said better handling and brakingfor sure.I asked about 25 or 30 more h.p.for the LS7 and he said within the parameters of emmisions, fuel mileage noise, and idle quality the LS7 is just about maxed out.He would not say for sure no h.p. bump but he seemed doubtful

You KNOW the Zr1 will have 650hp? Has this been announced and confirmed or is this your "guess"...?

Pio

If the LS7 is maxed out, I wont wait for the 09's.


That's what I've read around here, not at all sure. I mentioned the ZR1s' much higher (expected) out-put so noone would say - "if you want more power, go with a ZR1".

Since I'm not interested in the ZR1 - I dont know what the latest power rumors are.

It has enough HP to run 11.17 bone stock.
(well below the 11.50 limit imposed at most tracks).

Does it really need a bump in HP?

'06 Quicksilver Z06

With that type of capability is it really needed?

Foosh

Considering that virtually no one, who has risked their engine by adding 40-50 more HP, can match Ranger's stock 1/4 mile numbers, it certainly doesn't. It certainly doesn't need it on a road-racing course either. Brakes maybe, but not power.

It's the drivers who need a bump, not the car.

Pio

Yes, indeed the car has a bunch of power, no doubt about it. I just dont want to go through the same thing I went through when I got my 01 with 385 and then the 02's came out with 405.

I dont mind waiting a bit if more power is a year away.

Plus, Ranger ran quicker times with his 02 then with his 01 -so even a bit of more HP can make a difference. I know he could get a 10.99 out of a stock Z if it had just a hair more power.

Regardless, according to everyone that has chimed in, looks like 505 is the number.

TAILWAG

all very interesting...do we know what Ranger's car dynoed at? I would love to have him run my car....I bet he could see 10's...

'06 Quicksilver Z06

10.99 bone stock vs 11.1 bone stock on stock rubber, when you are talking those type numbers, the difference really doesn't matter. The average Z owner will never see either.

Sort of like having $200 million vs $201 million. When you are talking that kind of money, whats the difference? It would be hard to spend all of either.

Eventually, more power will be added stock--the question is when?

I would also bet on GM going to forced induction to get more power vs. larger displacement. If that is the case, then you might want to wait until they iron it out for a year or so. But then you will be right up against the advent of the C7Z. I would buy now. If you need more power beyond bolt-ons,go with the Viper--smog legal and warranty.

In the 2 times I have done HPDEs in my '06 Z (LGM headers w/cats; tune; K & N; BK harness bar; '08 rear shocks), more power was the LAST thing I needed! More driver, more tires, more suspension and bullet proof brakes, YES!! The car is a bit loose and floaty when pushed. Perhaps this is what the source listed above has indicated GM intends to address in 2009? However, aftermarket with Brembos and Pfadt would probably be better anyway.

Oh yeah, the stock seats are still a major embarrassment--like a '70s firebird or something, dressed in pleather!

There is so much power in the car it is silly on the road course--like a video game or a motorcycle. Now, if you are a drag racer or running the standing mile or top speed runs, etc., maybe that is different.

Of course, none of this answers your question!

PIO, your not getting bored of the SC?
Just tell Andy to put some bolt on's N/A

JZ

I say JUMP IN...the car is AWESOME in present form, and the 08 with improvements is the Best Vette Yet (IMHO)...besides, if you keep waiting for the next best to come along...you will just keep waiting, and waiting, and...

Pio

But the original question is if / when the Z getting any more power. See, I dont mind waiting one more year, IF the 09 will have a bit more power.

You might not know this, but I had one of the strongest 06 Z's on the forum (610+ rwhp / 580 rwtq) until recently that I parted with it.
And, currently have over 700 rwhp in my 03 Z - so its not that I'm craving any power, I just rather wait til 09 if its going to get a slight but, that's all.

In no way am I advocating that the current car needs more power. But, in a few years, I'd rather own the 525 hp Z over the 505 Z. Resale value should be stronger too, think about the premium an 02 Z gets over an 01.

10.99 and 11.1 are way too close to matter, but if you had the choice, wouldn't you want the one capable of turning the faster time?

Uhh, lets not go there that Z and I have parted ways...

'06 Quicksilver Z06

For me a few things would factor in Pio.

Willingness to wait, price, desirability and resale value. The latter two you have already alluded to.

Once you get quicker than mid 11s which is about as fast as I want to go, my priorities change.

Would I be willing to wait a year for a car capable of going a tenth or two quicker than 11.1?

I don't think so. A year is a long time to wait for a car offering a small HP increase. And I highly doubt a significant power increase.

For example we saw about a 9%-10% increase in the base C6 power levels. I doubt we see that kind of an increase in the Z06 to a 545 hp or 550 hp C6 Z06.

How much more would I be willing to pay for a car capable of improving upon 11.1 performance levels by about a tenth or two?

Not much.

How concerned am I about resale value and desirability?

I am very concerned about that and its at this point only where my interest in a power increase might peak.

A 525 hp version of the Z06 would almost certainly be more desirable 10-20 years from now than a 505hp version.

Sorry to hear....did I miss that thread .... wish you the best of luck

427Z

you could be dead in 09. live for today

I know where you guys are going in that the car needs some other items upgraded before more power is added. That is a legitimate point and it would be great to see that happen. That being said, if I were in Pio's shoes, I would probably wait if I knew next year's model were going to have a 20 HP increase. Some people just like the extra power and I don't think there is anything wrong with that.
